Application filed June s, 1921. serial No. 475,200.

To @ZZ whom t may conce/m:

Be it known that l, WILLIAM Wnnxnn, a citizen of the United States,residing at Aberdeen, in the county of Grays Harbor Vdomestic purposesand which will afford a relatively high efiiciencywith an economicalconsumption of fuel.

With these and other ends in view, the invention consists in the novelconstruction, arrangement and combination of parts hereinafter describedand claimed.

In the accompanying drawings,-

Figure 1 is aside elevation of an oil burner embodying my invention.Fig. 2 is a plan view of the same with one of the burner heads partlybroken away. Fig. 3 is a transverse section on broken line 3 3 of Fig.1.V Fig. 4 is a detail sectional view of one of the burner heads. Fig. 5is a vertical detail section through 5-5 of Fig. 2,

parts being omitted.

In said drawings, the reference numeral 10 designates a hollow basemember which is desirably rectangular in transverse section containing achamber 11.v This chamber serves as a reservoir for a mixture ofVhydro-carbon gas and air which is received from the end 12 of a pipe 13of less diameter than the chamber 11 and extendsrfrom one end of thelatter to about the midlength of the same.

The other end of the pipe 13 communicates through a return bend 141 witha receptacle 15 serving as a mixing chamber and located at one side ofthe basemember 10 adjacent to the inlet end of the pipe 13. Air isadmitted from below through an opening 16into the mixing chamber 15.

Plates 17 and 18 are removably secured to the receptacle to afford airtight closures for clean-out holeswhich are advantageously provided inthe top and in one side, respec# tively, of the receptacle. l

Connected to the receptacle 15 and in opposed relations with the inletend of the return bend 14 is the discharge element 20 of a substantiallyhorizontal coil of pipes 19 which constitutes a gas'generator withrespect to fuel oil delivered into the receiving element 21 of the coilfrom any suitable .source of supply, not shown. The fue] oil is suppliedinto said coil under pressure and to obviate its passing too rapidlytherethrough the pipe coil is advantageously provided interiorly with aporous retarding agent such, for example, as fibrous asbestos indicatedby 22 in Fig. 3.

The generating of gas from the oil is accomplished by meansv of asupplementary burner which is disposed below said coil and, as shown,comprises a horizontally arranged vessel 23 having orifices 24: in itstop for the discharge of fuel gas received from the reservoir 11 througha hollow bracket 25 provided at one side of the base member 10.

Generation of gas within said coil is started by burning oil-saturatedmaterial in troughs 26 provided in the top of themvcssel 23. Adjacent toeach of its ends the chamber 11 is provided with passages 27 extendingupwardly through tubular neck element-s 23 of the base member.

Said necks are desirably square in horizontal sections and terminate ininwardly sloping sides to afford inclined bearing surfaces 29 andupwardly converging outlets for the respective passages 27.

Surmounting each of said necks is a hollow burner 30 having the shape ofa parallelepiped comprising separable collar and head members 31 and 32.The collar inember 31 is in the nature of a rectangular vplate providedwith a central hub element 33 which extends upwardly into the head andhaving a central aperture corresponding in shape to the taperingextremity of the respective neck for seating upon the same. Said hub isalso provided with air inlet holes 3-1 which incline inwardl toward theaxis of the neck as shown in iig. 1. The head member 32 is providedalong the bottoms of its side and end walls with rabbets, such as 35, toreceive the supporting collar member 31.

The side walls 36 of said head member are each provided with a series ofhorizontal slits 37 through which the combustible gas-andair mixture isemitted to be consumed outside of the head.

Above the neck and hub in each head 30 is provided a cap piece 38 whichis recessed to fit over the hub and afford in its underside concavities39 to provide communicative connections betweenthe inlets 34 and thethroat passage in the neck which will direct
